Dual eDRX Paging Selection Across Mixed-Support Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of improving paging success rates for terminal devices in communication systems with evolving eDRX technologies, where devices may transition between cells supporting different eDRX cycles, leading to paging failures.
Innovation Solution
Implementing two types of eDRX configuration information based on the category of the access network device, with one type having a cycle greater than a threshold and the other less than or equal to the threshold, allowing the terminal device to adapt its monitoring behavior accordingly.

Engineering Contradiction Analysis
1Use of energy by moving object
If the eDRX cycle is continuously prolonged to keep the terminal device in sleep state for longer time, then power consumption is reduced, but paging failure occurs when the terminal device moves between cells with different eDRX cycle support
Solution Approach 1:
The patent applies parameter changes by configuring two different eDRX cycle parameters (first eDRX cycle and second eDRX cycle) based on the terminal device's capability and the access network device's support. The terminal device switches between these parameters depending on whether it is in a first cell (supporting longer eDRX cycle) or second cell (not supporting longer eDRX cycle), thereby optimizing power consumption while ensuring paging reliability across different network environments
Solution Approach 2:
The patent implements dynamics by making the eDRX cycle configuration adaptable and changeable based on the terminal device's location and the access network device's capabilities. The terminal device dynamically selects between first eDRX configuration information and second eDRX configuration information according to cell type, allowing the system to optimize power consumption in real-time while maintaining paging success rate
2Use of energy by moving object
If the terminal device uses a longer eDRX cycle to extend sleep time, then power consumption is reduced, but the terminal device cannot receive paging messages from access network devices that do not support the longer eDRX cycle
Solution Approach 1:
The patent applies universality by designing a dual-configuration eDRX mechanism that works with both old and new access network devices. The terminal device is configured with both first eDRX configuration information (for access network devices supporting longer cycles) and second eDRX configuration information (for legacy devices), enabling it to operate universally across different network environments without sacrificing power efficiency or compatibility
Solution Approach 2:
The patent changes the eDRX cycle parameter based on the access network device's capability. When the terminal device detects it is in a cell served by an access network device that does not support the first eDRX cycle, it switches to the second eDRX cycle parameter, ensuring compatibility while maintaining optimal power consumption for the given network environment

AI summary
This application provides a paging method and an apparatus. The paging method includes: A terminal device receives extended discontinuous reception (eDRX) configuration information of a first type and eDRX configuration information of a second type, where the eDRX configuration information of the first type includes a first eDRX cycle, the eDRX configuration information of the second type includes a second eDRX cycle, the first eDRX cycle is greater than a first cycle threshold, and the second eDRX cycle is less than or equal to the first cycle threshold; and the terminal device determines, based on a category of an access network device of a cell in which the terminal device is located, to monitor a paging message by using the eDRX configuration information of the first type or monitor a paging message by using the eDRX configuration information of the second type.
